I called Granite Doctor to ask about replacing an old under mount stainless steel sink that was ugly and way too small. I was ready to have it cut out and replaced with a top mount style, but Granite Doc talked me out of it. He explained that it was possible to cut out the old sink and polish the edges of the granite so that I could instead use a better looking under mount sink. Long story short - these guys did a great job for me. In fact after the sink was installed we noticed a dent in it that we all had not seen. They came back the next day with a replacement sink and replaced the first one! Great service and I now have a sink that really updated our kitchen.
